I have been brave enough to dismantle my tower and delve into the workings. Something in my PSU has blown and I need a new one but where do I find a DELTA PSU Model No. DPS-145PB-111 A REV (150W)??

You shoudn't need to replace the PSU with one exactly the same as the one you took out. Pop along to Maplins or even PC World with the old PSU and ask them to advise you one a suitable replacement.

Any other PC component shop should also be able to find you a suitable replacement.

Hmmm

150W is pretty low powered.

Most 'bought' PC's (ready-made) have about 250-300W.

More is better in case you need to add extras (DVD drive, extra Hard Drives, new Graphics card etc.) later on.

I'd suggest 350W would be a better bet.

This is a ROUGH guide to power usage. Add your components together to get the absolute minimum.

PSU: What you need
AGP video card - 20-30W
PCI video card - 20W
AMD Athlon 900MHz-1.1GHz - 50W
AMD Athlon 1.2MHz-1.4GHz - 55-65W
Intel Pentium III 800MHz-1.26GHz - 30W
Intel Pentium 4 1.4GHz-1.7GHz - 65W
Intel Pentium 4 1.8GHz-2.0GHz - 75W
Intel Celeron 700MHz-900MHz - 25W
Intel Celeron 1.0GHz-1.1GHz - 35W
ATX Motherboard - 30W-40W
128MB RAM - 10W
256MB RAM - 20W
12X or higher IDE CD-RW Drive - 25W
32X or higher IDE CD-ROM Drive - 20W
10x or higher IDE DVD-ROM Drive - 20W
SCSI CD-RW Drive - 17W
SCSI CD-ROM Drive - 12W
5400RPM IDE Hard Drive - 10W
7200RPM IDE Hard Drive - 13W
7200RPM SCSI Hard Drive - 24W
10000RPM SCSI Hard Drive - 30W
Floppy Drive - 5W
Network Card - 4W
Modem - 5W
Sound Card - 5W
SCSI Controller Card - 20W
Firewire/USB Controller Card - 10W
Case Fan - 3W
CPU Fan - 3W

this is interesting!
can I fit any PSU with a higher wattage rating?
thankyou for all your replies so far.

Hi Stoner,
Try a Computer Fair(if you are near to one) or the auction sites Ebay,QXL. I agree with
MartinT-B,150watts is too low.Most PSUs sold now are 250 to 350 watts.
I just hope you have not damaged the motherboard, as this will mean quite an expense.

  MartinT-B 16:15 14 Apr 03

As long as you buy one that fits your case

99% of the time that's an ATX case.

You can get them up to 540W to my certain knowledge, but unless it's a server tower with multiple SCSI HDD's, there's not point in that much overkill.

Add up what you need now and add 100W is my advice.

  stoner 16:23 14 Apr 03

saburini, what do you mean "damaged the motherboard"?
I don't think I like the sound of that!
How would I have done that .....?

The old type of power supply ?AT? the serial ports on your PC are usually on removable plates at the side of your other PCI gear, modem connections, graphic output and the like. Most of the PSU's sold today (and for the past 3 years or so) are 'ATX' where on your PC the serial ports are vertical (on a tower case) & on a single plate together with USB ports, & maybe speaker outputs. You can use a higher wattage PSU. Some not all'ATX' PSU have outputs for 'AT' cases/mainboards.

You may find that buying just a PSU is dearer than buying a new case complete with PSU.

As you mentioned that the PSU had blown,But for what reason? Usually,other component failures may cause this and there are an awful lot of them on the motherboard.
However,I dont wish to alarm you too much,just be prepared for more expense.PSU's are generally cheap (even a new case only adds about a tenner).
If you follow all the advice given you wont go too far wrong.It strikes me though that you must have access to a working computer to answer all the replies, so the best of luck and happy diagnosis.
